Is it possible to somehow track the folding and opening of the application? I am writing a player, I would like it to stop when the application is minimized, and when I open it, I start playing

    In UIApplicationDelegate : there are methods that are called in appropriate situations:

    applicationWillResignActive: - called when the application is minimized

    applicationWillEnterForeground: - called when the application becomes active

    Or there are system notifications:

     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillResignActive:) name:UIApplicationWillResignActiveNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillTerminate:) name:UIApplicationWillTerminateNotification object:nil];
